Abstract:
A method for preparing a nanometal-polymer composite conductive film includes the steps of (1) mixing a metal oxide with a polymer solution; (2) coating a substrate with a solution resulting from step (1), followed by drying the resultant solution to form a film; (3) performing thermal treatment on the film formed in step (2); and (4) sintering the film thermally treated in step (3). The method dispenses with any reducing agent or dispersing agent but allows nanometallic particles to be formed in situ and thereby reduces surface resistance of the polymer film efficiently.

Abstract:
A method of removing an alumina layer around a main pole layer during perpendicular magnetic recording head fabrication is disclosed. The alumina etch sequence includes immersing a substrate in a series of aqueous solutions purged with an inert gas to remove oxygen thereby avoiding corrosion of the main pole. Initially, the substrate is soaked and heated in deionized (DI) water. Once heated, the substrate is immersed in an etching bath at about 80° C. and pH 10.5. Bath chemistry is preferably based on Na2CO3 and NaHCO3, and N2 purging improves etch uniformity and reduces residue. Thereafter, the substrate is rinsed in a second DI water bath between room temperature and 80° C., and finally subjected to a quick dump rinse before drying. Inert gas, preferably N2, may be introduced into the aqueous solutions through a purge board having a plurality of openings and positioned proximate to the bottom of a bath container.
Abstract:
In various embodiments, a system is used to provide an apparatus configured to measure sound in an ear canal of a wearer's ear at a distance from a tympanic membrane of the ear. The sound is measured and received by the apparatus to produce a signal. A frequency analysis is performed on the signal to determine output as a function of the frequency and to determine the frequency of the minima (null). Further, a distance equal to a quarter wavelength of the null frequency is calculated. A correction factor associated with the quarter wavelength is retrieved and applied to the output to generate a corrected output. An estimated sound pressure level at the tympanic membrane from the corrected output is produced.

A signal transmission system of a flat panel device includes an encoder, a transmitter, a receiver, and a decoder. The encoder converts a digital signal to a switch control signal. The transmitter includes 4n signal-lines for transmitting a current signal according to the switch control signal. The receiver includes 4n terminations, a plurality of terminal resistors, and a plurality of comparators. The receiver generates a group of voltage levels according to the current signal. Each comparator is coupled between any two terminations so as to generate a group of voltage differences. The decoder converts the group of voltage differences to the digital signal.
Abstract:
A trap with a housing having a first wall, an entrance, and a base; a latch mechanism coupled with the base; a pivoting platform pivotally coupled with the housing adjacent a juncture of the base and first wall and adapted to releasably engage with the latch mechanism; and a trigger plate assembly including a first trigger plate and a second trigger plate that are pivotally coupled with the pivoting platform. The first trigger plate is operably coupled with the latch mechanism and the second trigger plate is operably coupled with the first trigger plate. When the trap is triggered by an animal, the pivoting platform disengages from the latch mechanism and the pivoting platform and trigger plate assembly pivot toward the first wall of the housing, moving the rodent toward the first wall of the housing and trapping the rodent between the trigger plate assembly and the first wall of the housing.
Abstract:
A method for dynamically adjusting the power consumption of a multi-carrier receiver and a multi-carrier receiver with dynamically power adjustment. The method includes receiving a multi-carrier signal, wherein the multi-carrier signal comprises a plurality of sub-carriers. Channel characteristics of each sub-carrier are estimated according to the demodulated multi-carrier signal. ICI is estimated from the demodulated multi-carrier signal. A system performance is detected. The estimated ICI is subtracted when the ICI exceeds an ICI threshold and the system performance is less than a system performance threshold. The demodulated multi-carrier signal is then equalized is based on the estimated channel characteristics, and the system performance is updated according to the equalized multi-carrier signal.
Abstract:
A method for labeling connected components and a computer system using the method are provided. With the method, during a process of scanning an image for the first time, each object pixel in the image is assigned a temporary label, and a relationship between each temporary label and a representative label is established after the completion of the process of scanning the image for the first time. Thereafter, the temporary label of each object pixel is replaced by the corresponding representative label during a process of scanning the image for the second time. As a result, the labeling of the connected components can be accomplished by only scanning the image twice such that the efficiency of labeling the connected components can be significantly improved.
